On the basis of static aerodynamic force tests and dynamic response tests, the galloping and (vortex-induced) oscillation performances of H-shaped booms were investigated.
通过节段的静力和弹簧悬挂动力试验，对H型吊杆的驰振和涡激振动性能进行分析。
Then the vortex-induced vibration response of cables is calculated.
从而计算拖缆的涡激振动响应。
Vortex-induced vibration is limited amplitude response, but it occurs at low wind speed with relative large amplitude, which will affect the strength and fatigue resistance of the structure.
尽管涡振是一种限幅振动，但由于其发生风速较低，振幅相对较大，会影响结构的强度和疲劳，因此大跨度拱桥的涡振响应研究具有重要的意义。
